SHANGHAI: Development and operation of interconnections in a restructuring context

Summary

Due to unexpected event in China (SARS), Symposium was held on April 4-6, 2004, in Ljubljana, Slovenia

In many countries the electrical network is not fully interconnected and the best technical solution to achieve interconnection has to be found.

At the same time the electricity industry is being restructured and interconnecting independent energy markets presents technical challenges. It is therefore timely to consider interconnection development and operation options:

• examine the benefits of interconnecting electrical networks and the development strategies,
• review the interconnection design options and the technologies available,
• identify the operational issues, the security problems of large interconnected systems, the protection issues,
• consider the impact of the restructuring of the electrical supply industry,
• assess the political, environmental and social implications of interconnections.
